The U.S. and several other countries levy tariffs on certain goods and impose other trade restrictions that may impact our customers' investment in manufacturing equipment, reduce the competitiveness of our products, or inhibit our ability to sell products or purchase necessary equipment and supplies. In particular, trade tensions between the U.S. and China have been escalating since 2018, with U.S. tariffs on Chinese goods and retaliatory Chinese tariffs on U.S. goods, and there remains significant uncertainty about the future relationship between the U.S. and China. We cannot predict what further actions may ultimately be taken with respect to tariffs or trade relations between the U.S. and other countries, what products may be subject to such actions, or what actions may be taken by other countries in response. Further changes in trade policy, tariffs, additional taxes, restrictions on exports or other trade barriers, or restrictions on supplies, equipment, and raw materials, may limit our ability to produce products, increase our selling and/or manufacturing costs, reduce the competitiveness of our products, or inhibit our ability to sell products or purchase necessary equipment and supplies, which could have a material adverse effect on our business, results of operations, or financial condition.
Though nearly all of our manufacturing activities take place outside of the U.S., certain of our advanced packaging products are subject to the EAR because they are based on U.S. technology or contain more than a de minimis amount of controlled U.S. content. The EAR require licenses for, and sometimes prohibit, the export of certain products. The CCL sets forth the types of goods and services controlled by the EAR, including civilian science, technology, and engineering dual-use items. For products listed on the CCL, a license may be required as a condition to export depending on the end destination, end use or end user and any applicable license exceptions.
In 2020, the U.S. Department of Commerce Bureau of Industry and Security ("BIS") amended the EAR to expand controls on certain foreign products based on U.S. technology and sold to Huawei and certain other companies. In October 2022, the BIS amended the EAR again to extend those foreign controls to numerous companies on BIS' so-called Entity List. The 2020 and 2022 amendments impact some of our advanced packaging products, which are based on U.S. technology and are within the scope of the expanded EAR controls on Huawei and other Entity List companies. Therefore, these products cannot be sold to Huawei and other Entity List companies, and are subject to certain end-use restrictions. To date, these amendments to the EAR have not had a material direct impact on our business, financial condition or results of operations and we do not expect that they will, although they could have indirect impact, including increasing tensions in U.S. and Chinese trade relations, potentially leading to negative sentiments towards U.S.-based companies among Chinese consumers. Additionally, some end users may prefer to avoid the U.S. supply chain in its entirety to avoid the application of these regulations.
In November 2023, the BIS issued additional rules to update export controls on advanced computing semiconductors and semiconductor manufacturing equipment, as well as items that support supercomputing applications and end-uses, to arms embargoed countries, including China.
We are taking appropriate measures to comply with all applicable BIS Rules. Where required, we will apply for export licenses from the BIS to avoid disruption to our customers' operations. Export licenses may be subject to a prolonged review and appeals process, to which there cannot be an assurance as to whether an export license may be granted, granted with conditions or eventually revoked due to subsequent challenge.
Additionally, the rules promulgated by the BIS are typically complex, and the BIS could revise or expand them in response to public comments. Likewise, the BIS may issue guidance clarifying the scope of the rules. Such revisions, expansions or guidance could change the impact of the rules for our business.
Future changes in, and responses to, the various export regulations, tariffs, or other trade regulations between the U.S. and other countries may be unpredictable. Such further changes may limit our ability to produce products, increase our selling or manufacturing costs, decrease margins, reduce the competitiveness of our products and cause our sales to decline, and therefore could have a material adverse effect on our business, financial condition or results of operations.
